OPA4137U

Texas Instruments · FET Input Amplifiers · SOIC-14

OPA4137U from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	Out A	output	Output of amplifier A, which can swing to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V.
2	-In A	input	Inverting input of amplifier A; input current should be limited to 2mA when the input exceeds the supply rails.
3	+In A	input	Non-inverting input of amplifier A; common-mode range runs from (V-)+3V to (V+).
4	V+	power_in	Positive supply, 4.5V to 36V single-supply (±2.25V to ±18V dual), bypassed with a 10nF or larger ceramic capacitor.
5	+In B	input	Non-inverting input of amplifier B; common-mode range runs from (V-)+3V to (V+).
6	-In B	input	Inverting input of amplifier B; input current should be limited to 2mA when the input exceeds the supply rails.
7	Out B	output	Output of amplifier B, which can swing to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V.
8	Out C	output	Output of amplifier C, which can swing to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V.
9	-In C	input	Inverting input of amplifier C; input current should be limited to 2mA when the input exceeds the supply rails.
10	+In C	input	Non-inverting input of amplifier C; common-mode range runs from (V-)+3V to (V+).
11	V-	power_in	Negative supply or ground in single-supply use; total supply (V+ to V-) is 4.5V to 36V (±2.25V to ±18V).
12	+In D	input	Non-inverting input of amplifier D; common-mode range runs from (V-)+3V to (V+).
13	-In D	input	Inverting input of amplifier D; input current should be limited to 2mA when the input exceeds the supply rails.
14	Out D	output	Output of amplifier D, which can swing to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V.
